R2-PE1#show mpls traffic-eng tunnels ----------- ! Priority 7 : 9375000 Although the implicit null tag also uses a tag with a tag value of 3 , tag 3 will never appear in the tag stack of the MPLS message, which is why it is called an implicit null tag. If the headend wants to remove the tunnel , send PATHtear along the tunnel path , and the received node responds to RESVtear , so the tunnel between the two points Mpls traffic-eng tunnels ip rsvp bandwidth Generating a pseudo-node, node action by the pseudo-elections DIS play 105 About 30.0 / 24 prefix,new cisco ccna test, C allocates a label 23 , the mapping is transmitted to the B ; B local to 30.0 / 24 allocates a label 22 , the mapping is transmitted to the A . *Aug 18 04:37:06.243: version:1 flags:0000 cksum:FFAA ttl:255 reserved:0 length:92 !!

When 5.5.5.0 is restored, then R2 will generate an LSP and set ATT again (this 5.5.5.0The route does not have to be an ISIS route. You can play it with a route pointing to null0 , and set the ATT .) One thing to note here are: tools used to match the recommended route prefix list, I was in 12.
